Fig. 1 shows an exploded view of a shrink tube mounting device provided by an embodiment of the present disclosure, as shown in fig. 1 and 2, the shrink tube mounting device may include:

the tool comprises a tool main body 1 and a baffle plate 2, wherein the tool main body 1 is in a sleeve state, and the baffle plate 2 is provided with an open slot 2a;

The tool main body 1 is provided with a rivet positioning hole 1a and a baffle inserting hole 1b (shown in combination with fig. 3) matched with the baffle 2;

As shown in fig. 1 and 3, the flap insertion hole 1b has an insertion hole 1c provided on the outer surface of the tool body 1, and extends from the insertion hole 1c to the inner wall cut off from the rivet positioning hole 1 a.

With the shrink tube mounting device of the embodiment, referring to fig. 1-3, the tooling main body 1 is first sleeved on the shrink tube connection region, and the rivet positioning holes 1a are aligned with the rivet mounting holes 3a of the shrink tube connection region; then placing the rivet 4 into the rivet mounting hole 3a through the rivet positioning hole 1 a; then, the baffle plate 2 is inserted into the baffle plate jack 1b through the jack 1c, at the moment, the opening of the opening slot 2a firstly enters the baffle plate jack 1c until the baffle plate 2 stretches into the rivet positioning hole 1a, the rivet 4 is limited in the opening slot 2a in the stretching process, and the baffle plate 2 plays a limiting and restraining role on the rivet 4.

All rivets 4 are restrained in place as described above. In this state, the following caulking operation is performed one by one for the rivets 4: the corresponding retainer 2 is pulled out to expose the rivet positioning hole 1a, and the rivet 4 is riveted in place by using a rivet gun. When riveting a certain rivet 4, other rivets 4 are restrained by the baffle plate 2 and cannot pop out due to impact force generated by a rivet gun, so that the installation stability and the installation efficiency are improved. Meanwhile, the embodiment can realize single installation, thereby saving labor and reducing cost.

In the embodiment of the present disclosure, as shown in fig. 1, four rows of rivet mounting holes 3a (left and right lower sides are hidden from view) corresponding to the shrink tube mounting region, the tool body 1 is provided with four rows of rivet positioning holes 1a, wherein the rivet positioning holes 1a are in one-to-one correspondence with the rivet mounting holes 3 a. The number and the position of each row of rivet positioning holes 1a on the tool main body 1 can be adjusted according to the needs, the diameter of each rivet positioning hole 1a can also be adjusted according to the diameters of different rivet gun heads, and the width of the open slot 2a can also be adjusted according to rivets of different types.

In the embodiment of the disclosure, as shown in fig. 1 and 2, the tool main body 1 includes two detachably connected parts, namely, a first tool 11 and a second tool 12, and the first tool 11 and the second tool 12 are in a sleeve shape in a connection state.

In the application process, the first tool piece 11 and the second tool piece 12 can be half sleeved outside the shrinkage pipe connection area and are in butt joint. And after all rivets are installed, all the baffle plates 2 are detached, then the first tooling piece 11 and the second tooling piece 12 are detached, and the first tooling piece 11 and the second tooling piece 12 are removed.

The frock main part 1 of this embodiment adopts split type structure, is applicable to the waiting connecting piece size longer based on the mounting means of draw, and from both sides butt joint equipment frock main part 1 this moment, feasibility and stability are all higher. In another embodiment, if the size of the to-be-connected piece is shorter, the to-be-connected piece can be sleeved on the to-be-connected piece from two ends and translated to the contracted pipe connecting area, and then a split structure is not needed.

In one embodiment, the first tooling member 11 and the second tooling member 12 are removably connected using a latch 5. In the connection state, the bolt 5 passes through the connecting part 13 correspondingly arranged on the first tool piece 11 and the second tool piece 12 to connect the two parts together. The mode is convenient to disassemble and assemble, and time is saved.

In the embodiment of the present disclosure, the open groove 2a provides a certain elastic deformation space of the flap 2. Thus, when the baffle plate 2 enters the baffle plate insertion hole 1b (shown in fig. 3) through the insertion hole 1c (shown in fig. 1) to be extruded and deformed, the width of the opening groove 2a is narrowed, and when the baffle plate 2 is inserted into place, the baffle plate 2 can be blocked in the baffle plate insertion hole 1b, so that the baffle plate is not easy to fall off.

In the embodiment of the present disclosure, as shown in fig. 4, the baffle plate 2 has both side surfaces facing away from the open groove 2a, and the protrusions 20 are provided at the opening positions of the side surfaces near the open groove 2 a. In the process of installing the baffle plate 2, as shown in fig. 3, due to the protrusions 20, the two sides of the opening groove 2a of the baffle plate 2 are pressed to elastically deform, and when the protrusions 20 penetrate out of the baffle plate insertion holes 1b, the elastic deformation of the baffle plate 2 disappears and returns to its original shape. At this time, the protrusion 20 plays a limiting role on the baffle 2, so that the baffle 2 is prevented from exiting from the baffle jack 1b, the stable retaining position of the baffle 2 is ensured, and the riveting reliability and stability of the rivet 4 are improved.

In the corresponding embodiment, the width Z of the flap 2 at the position corresponding to the protrusion 20 is larger than the width O of the flap insertion hole 1b, so that the flap 2 is elastically deformed when passing through the flap insertion hole 1 b. Further, the width Z of the baffle 2 at the position corresponding to the protrusion 20 is not greater than the diameter of the rivet positioning hole 1a, so that when the protrusion 20 of the baffle 2 passes through the baffle insertion hole 1b, the elastic deformation of the baffle 2 disappears and pops out to two sides, and at this time, the rivet positioning hole 1a provides a receiving space for the baffle 2 to pop out to two sides.

In another embodiment, the width of the rest of the baffle 2 except the protrusion 20 is slightly smaller than the width of the baffle insertion hole 1b, and the overall thickness of the baffle 2 is uniform but lower than the height of the baffle insertion hole 1b, which enables the baffle 2 to be easily pushed in and pulled out.

Further, the width X of the open slot 2a is larger than (the rivet head diameter y+ (Z-O)), so that the width Z of the flap 2 at the position of the protrusion 20 is not excessively large, avoiding the situation that it cannot be inserted into the socket 1c (as shown in fig. 1) even in the form of limited elastic deformation, which may be set according to the specific form of the flap 2 and the size of the flap socket 1c, which is not limited herein.

In the disclosed embodiment, the width X of the open slot 2a is not greater than the maximum diameter R of the shank of the rivet 4, e.g., X is slightly less than R or X is equal to R, such that when the flap 2 is inserted into place, the rivet 4 is captured in the open slot 2a by the shank, and the flap 2 forms a stable stop for the rivet 4 through the open slot 2 a.

In the embodiment of the present disclosure, as shown in fig. 4, the protrusion 20 has an arc shape. Thus, as shown in fig. 3, when the shutter 2 moves in the shutter insertion hole 1b, the circular arc protrusion 20 does not scratch the inner wall of the shutter insertion hole 1b, thereby improving the product life.

In the embodiment of the present disclosure, as shown in fig. 3, the flap insertion hole 1b extends from the insertion hole 1c to the inner wall of the rivet-positioning hole 1a in a direction perpendicular to the central axis of the rivet-positioning hole 1 a. In another embodiment, other included angles are formed between the extending direction of the baffle inserting hole and the central axis of the rivet positioning hole, and at this time, the baffle inserting hole can be slightly inclined without affecting the baffle inserting operation.

In the embodiment of the disclosure, as shown in fig. 1, the distance from the lower plane of the baffle insertion hole 1b to the bottom of the inner wall of the rivet positioning hole 1a is higher than the highest point of the collar 40 exposed after the rivet 4 is inserted into the rivet mounting hole 3a, so that the baffle 2 is ensured not to be blocked on the collar 40 of the rivet 4 when being inserted, and can play a role of stopping the collar 40.

The overall shape of the tool body 1 of the embodiment of the disclosure is matched with the shrink tube installation area, and as shown in fig. 2, the shrink tube installation area is square, and then the tool body is square as a whole.

In another embodiment, as shown in fig. 5, if the interface of the shrink tube mounting area is circular, the tool body 10 is correspondingly designed to be circular. As shown in fig. 6 and 7, if the sections of the shrink tube mounting areas correspond to the shapes, the tool main body 100 is correspondingly designed to have the corresponding shapes.

The sections of the shrink tubes, which can be used for connection, of the tool body in the embodiment of the disclosure include, but are not limited to, R-angle rectangular, D-shaped, circular, polygonal or other irregular sections, and the like, and the tool body 1 can adjust the contour of the inner ring of the tool body 1 according to the contour of the sections of the respective shrink tubes.

The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
